drm/mesa/ati R5xx 3D support: What is the correct compilation order?

[Stefan Becker]

Hi,

I tried to follow Alex's blog entry under

    <http://www.botchco.com/agd5f/?p=27>

but I can't get any 3D to work on my Lenove T60 (Mobility X1300) with 
Fedora 9. It uses xorg-x11-server-Xorg-1.4.99.901-29.20080415.fc9, i.e. 
a relatively new xserver git.


Here is the order I figured out:

   F9 libdrm RPM:
    - update source from 
<http://cgit.freedesktop.org/~agd5f/drm/?h=r345-cleanup>
    - build
    - install

   F9 mesa RPM:
    - update source from 
<http://cgit.freedesktop.org/mesa/mesa/?h=r500-support>
    - build
    - install

   xf86-video-ati driver:
    - update to latest git
    - compile
    - install

   kernel drm & radeon module:
    - take source from libdrm RPM created above
    - in linux-core: make DRM_MODULES=radeon
    - copy radeon.ko & drm.ko to /lib/modules/$(uname -r)/updates
    - depmod -ae
    - remove old modules from memory: modprobe -r radeon

   start X server:
    - AIGLX now uses HW acceleration:

(==) AIGLX enabled
(II) AIGLX: Screen 0 is not DRI2 capable
(II) AIGLX: enabled GLX_MESA_copy_sub_buffer
(II) AIGLX: enabled GLX_SGI_swap_control and GLX_MESA_swap_control
(II) AIGLX: enabled GLX_texture_from_pixmap with driver support
(II) AIGLX: Loaded and initialized /usr/lib/dri/r300_dri.so

   - glxinfo shows HW renderer is enabled

   - glxgears (and others) still fail:

Warning, RV515 detected, 3D HAHAHAHAHA!!.
Mesa program:
-------------
# Fragment Program/Shader
   0: MOV OUTPUT[0], INPUT[1];
   1: END
drmRadeonCmdBuffer: -22

According to /usr/include/asm-generic/errno-base.h:

#define EINVAL          22      /* Invalid argument */

So it seems that the driver/DRI/DRM/mesa/AIGLX framework now plays 
correctly together to detect r5xx HW 3D acceleration. But the mesa code 
still can't submit microcode to the r5xx HW: mesa's r300 command buffer 
flush is the source of the "drmRadeonCmdBuffer: -22" error message.


Am I missing something here or is it just that 3D still doesn't work for 
the RV515 chip? It might be a good idea to post another blog entry with 
the correct installation order so that uninitiated dummies like me can 
get it right too...


HW info:

01:00.0 VGA compatible controller: ATI Technologies Inc M52 [Mobility 
Radeon X1300]
01:00.0 0300: 1002:7149
(--) RADEON(0): Chipset: "ATI Mobility Radeon X1300" (ChipID = 0x7149)

Regards,

	Stefan
